Generating QR codes in Visual Basic 6.0 requires external solutions, such as the open-source VbQRCodegen library, REST API calls for online functionality, or COM-based SDKs like ByteScout. The most common approach for offline applications is using the VbQRCodegen library, while APIs offer a lightweight, dependency-free alternative. For the full source code using the VbQRCodegen library, visit wqweto/VbQRCodegen on GitHub wqweto/VbQRCodegen: QR Code generator library for VB6/VBA

For pure without external dependencies? Unfortunately, you cannot generate QR codes purely in native VB6 from scratch—the Reed–Solomon error correction and masking algorithms are too intensive, and VB6 lacks bitwise array speed. However, you can integrate existing free libraries.
